My sister bought one of the Sumita Eyeliner Pencil sharpeners from here. I have to say, it worked VERY well! Much better than the store bought one I have. I didn't think it would make a difference, a sharpener is a sharpener, right? Wrong! With the Sumita sharpener, I didn't loose as much product in it as I did with my store bought one, which is key with a pencil eyeliner! I love my Sumita eyeliner so much, I will be purchasing a sharpener myself. I took all the restraint I had not to steal my sisters'! *Grin* Birchbox, thanks again for introducing me to Sumita! Both of us sisters are a HUGE fans!
